In heavy equipment operation, maintaining smooth hydraulic and transmission performance is crucial for ensuring the equipment runs efficiently. The Terex TA27 is a popular machine in construction and heavy lifting, but like any other equipment, it can face operational issues. One such issue reported by users is a surge in transmission or hydraulic pressure, which can lead to performance problems if not addressed promptly.
Symptoms of the Pressure Surge Problem
The most common symptom of a pressure surge in the Terex TA27 is a sudden increase or fluctuation in hydraulic or transmission pressure during operation. This surge can cause the machine to operate erratically, making it difficult to control, and can lead to excessive wear on components. A pressure surge often occurs when the hydraulic system or transmission is not functioning within its normal operating parameters.
Causes of Pressure Surge in Terex TA27
Several factors can contribute to a surge in pressure. Some of the common causes include:
To effectively address the pressure surge problem in the Terex TA27, follow these troubleshooting steps:
Addressing the transmission or hydraulic pressure surge in the Terex TA27 requires a thorough inspection of the machine’s critical components, including the pressure relief valve, hydraulic fluid, and transmission parts. Regular maintenance and proper operational practices are key to preventing such issues. By following these troubleshooting steps, you can help ensure that your Terex TA27 operates efficiently and remains in good working condition for years to come.

Causes of Pressure Surge in Terex TA27
Several factors can contribute to a surge in pressure. Some of the common causes include:
- Faulty Pressure Relief Valve: If the pressure relief valve in the hydraulic or transmission system becomes worn out or fails, it can no longer regulate the pressure properly, leading to surges.
- Contaminated Hydraulic Fluid: Dirty or contaminated hydraulic fluid can cause blockages and improper flow within the system, which might lead to pressure spikes.
- Damaged Hydraulic Pump or Transmission Components: Wear and tear on critical components, like the hydraulic pump or transmission, can lead to fluctuating pressures, especially when the system is under load.
- Air in the System: Air trapped in the hydraulic or transmission system can cause irregular pressure, leading to surges during operation.
To effectively address the pressure surge problem in the Terex TA27, follow these troubleshooting steps:
- Inspect the Pressure Relief Valve: The first step is to check the pressure relief valve. If it is malfunctioning, replacing it with a new one can solve the pressure surge issue.
- Check Fluid Quality: Inspect the hydraulic fluid for contamination or dirt. If necessary, replace the fluid and clean the filters to ensure the system operates smoothly.
- Examine the Hydraulic Pump and Transmission Components: Check for wear on the hydraulic pump, transmission gears, and related components. Any damage to these parts should be repaired or replaced immediately.
- Bleed the System: If air is suspected in the system, it is essential to properly bleed the hydraulic lines and transmission to remove trapped air.
- Monitor Operating Conditions: Always ensure that the Terex TA27 is being operated within the manufacturer’s recommended parameters. Overloading the machine can stress the system and lead to pressure issues.
